for operating a Siphon, for the withdrawal of l liquids from avat, tank or from any recep'r taclev where access cannotl be readily hadto the contents. j l j 1 A common method of creating a vacuum in l@ rubber hose or the like, has been to insertone end of the hose inthe liquid to be raised and then squeezing and rubbing the hose between the thumb and forefinger in a direction to-` ward the open end of the hose. This method of creating a vacuum is at best an awkward and trying operation requiring considerable strength, and is not always very satisfactory, especially when a liquid of high viscosity is toY be siphoned, such as a heavy vgrade of automobile oil or the like.

Another means Vof startinga Siphon is by sucking the air from the hose at its outer end.

It is obvious that this method is limited to the nature of the liquid to be siphoned. l For in-V stance noone would attempt to Suck into his mouth gasoline, lubricating oil, denatured alcohol or any Such unwholesome liquid. U

One of the important objects of this invention is 'to provide means for positively and quickly creating a vacuum iny a rubber hose or tube regardless of the nature ofthe liquid, as to either its wholesomeness or viscosity.

Another important object kof the invention Iis its Simplicity of construction and oper-Y ation. The device consists of a minimum of parts and can be economically manufactured and marketed. Y

` Other and further important objects of the invention Will be apparent from the disclosures in the accompanying drawings and` following specification.V

The invention, in a preferred form, is illustrated in the drawings and hereinafter more fully described. 'Y n In the drawings: Figure 1 is a side elevation of the invention, illustratingjit in operative position. Figure 2 is a top plan view of. the device, showing a sectional view of the compressed hose. i

ed to be positioned ,between rollers 12 and 14 mounted on arms 18 .and 2() of the apparatus. The'roller 12 is preferably constructed inthe shape ofl afcapstan drum, thel two ends'of which -terminatelin radial flanges 16. )The drum` 14 is preferably of 'a `v crown face construction,l the rolling surface of which is adapted vto register with the convexv Surface kof thedrum 12. f

The two drums 12V and 14 arerotatably mounted uponthe upper ends of a set of tongs having arms 18 and 20 respectively. Both of the arms 18 and'20 form parts of one con-` tinuousrod, formed atjits middle to provide a helical spring 22. rEach'of the outer ends of the arms'18 and 20'isbent at an angle of approximately 45 degrees toward each other, the ends of the arms ycrossing at right angles to each other'.V Atusubstantially their outer ends Vthe armsgare again bentat rightfangles Y to themselves, each portion sov bent being parallel to the other. It is upon these last mentioned bent portions that the rollers 12 and 14 are journaled. Lateral motion of the rollers is prevented by meansof the retaining nuts 24 and 26 atthe inner and outer ends of the drums respectively;

' A modification of tle invention islshown in Figure 4, rollers 28 'and 30 eachhave fiat rolling SurfaceS,-tli e roller 28 bein'gprovided with the radial flanges as Shown at 1S, and
